Unable to restart the keystone services

[Shruti Vasudeo]

While installing the devstack (liberty version) on CentOS 7 we are getting the following exception:

[Steve Martinelli (stevemar)]

the crux of this bug is keystone's use of "deprecated_reason", a config option exposed by oslo.config as of release 3.2.0 or newer.

what i'm confused about it the mention of "liberty" in the bug description - since keytone only started to use "deprecated_reason" in mitaka. (https://github.com/openstack/keystone/commit/cedba776142f6772ef1392eb5e5d54b969d8669c)

seems like the master version of keystone is being used with liberty oslo requirements, which won't work.
